Description

[Detailed description of the invention] This invention relates to an improvement of a heat insulating composite board in which a fiber-reinforced cement board is integrally laminated to a foam heat insulating material.

Hitherto, this type of composite plate has been known as disclosed in Japanese Utility Model Application Publication No. 55-119816, which is constructed as shown in FIG. Reference numeral 21 indicates a composite board, and this composite board 21 is made by integrally laminating a fiber-reinforced cement board (hereinafter simply referred to as a cement board) 23 on a foam insulation material 22, and a flange at one end is placed at an appropriate place such as a corner of the composite board 21. A female threaded cylinder 25 is provided with a female threaded cylinder 24 embedded therein.
A mounting rod introduction hole 26 communicating with the open end of the tube 5 is provided in the heat insulating material 22, and a mounting rod 27 having a T-shaped head 28 is introduced through this introduction hole 26, and its tip is screwed into the female thread tube. entered.

When using such a composite board 21, as shown in FIG. It is connected to the formwork 30 by a rod 31, a second connecting rod 32, nuts 33, 34, a threaded cylinder with a flange 35, and a nut 36, and the composite plates 21 are joined at their peripheral ends to form a front section. Formwork is formed, and then concrete is poured between both formworks to form a concrete frame 37. After that, the nuts 34, 36, the second connecting rod 32, and the formwork 30 are removed, and the composite plate 21 and concrete frame are removed. A heat insulating wall 38 with 37 bonded thereto is obtained.

However, in such a heat insulating wall, when an external force F is applied as shown in FIG. Since it is difficult for concrete, especially glass fiber, to enter the part, the tensile force is smaller than the tensile force, and therefore the bonding strength between the cement board 23 and the female threaded cylinder 25 is not sufficiently satisfactory, and the composite board 21 falls off from the concrete frame 37. There is a risk of

Furthermore, the female threaded cylinders 25 and the mounting rod 27 must be provided with a head 28 and a collar 24, which are connected to each other by means of screwing means, resulting in a disadvantage that the manufacturing cost is high.

The purpose of this invention is to provide a heat insulating composite board that eliminates the drawbacks of the conventional products mentioned above, can be firmly fastened with almost no risk of falling off from a concrete frame, and can be manufactured at low cost.

In order to achieve the above-mentioned object, this invention has a through hole provided at a suitable location in the heat insulating material, and this through hole has a substantially U-shaped curved portion made of wire;
The curved part of the mounting bracket, which is comprised of a base extending outward from both proximal ends of the curved part, is fitted into the base of the mounting bracket, which is filled with a heat insulating material, and in which the curved part is arranged. It is characterized by being embedded in a cement board.

Examples of the invention will be described below.

In Figures 4 and 5, 1 is a composite board, and this composite board 1 consists of a plate-shaped foam insulation material 2 and a glass fiber reinforced cement board 3, which are integrally laminated with each other, and the fibers are made of glass fiber. It is not necessary. Through holes 4 are provided at appropriate locations such as corners of the heat insulating material 2. 5 is a mounting bracket made of wire such as wire, approximately U.
It consists of a letter-shaped curved part 6 and a base part 7 extending outward from both base ends of this curved part 6, and the curved part 6 is arranged in the through hole 4, and the base part 7 is connected to the cement board 3. is buried inside. To manufacture the composite board 1 having the above-mentioned mounting fittings 5, as shown in FIG. The material 2 is placed on an uncured glass fiber-filled cement board 3 on the formwork 9.
The heat insulating material 2 is placed on top of the cement board 3 by pressing from above the heat insulating material 2 to the cement board 3, and the base 7 of the mounting fitting 5 is buried in the cement board 3. After that, when the cement board 3 is cured, the heat insulating material 2 and the cement board 3 are integrally laminated, and the mounting bracket 5 and the cement board 3 are stacked together.
A composite plate 1 in which the two parts are firmly and integrally bonded together can be obtained. In the above, when the base 7 of the mounting bracket 5 is buried in the cement board 3, the curved part 6 is inserted into the through hole 4 of the heat insulating material 2, so there is no possibility that the mounting bracket 5 will fall or the buried position will be changed. It allows for accurate and easy burial without having to do anything. 2' is a heat insulating material filled in the through hole 4 of the heat insulating material 2 integrated with the cement board 3.

When using such a heat insulating composite board 1, as shown in FIG.
3, 34, 36, and the rear formwork 30 through the flanged threaded cylinder 35, the composite plates 1 are joined at their peripheral ends to form a front formwork, and the front formwork formed in this way is Reinforcing bars 29 are installed between the part formwork and the rear formwork 30.
Install. Next, the reinforcing bars 29 and the mounting fittings 5 are connected by a binding material 10 such as a wire, and concrete is poured thereon to form a concrete frame 37. After that, nuts 34, 36, second connecting rod 3
2 and the formwork 30 are removed, a heat insulating wall in which the composite board 1 and the concrete frame 37 are firmly connected is obtained.

When an external force is applied to the heat insulating wall, the composite board 1 is firmly connected to the concrete frame 37 by the mounting bracket 5, and the base 7 of the mounting bracket 5 allows the glass fiber to be inserted into the surrounding area in just the right amount. Since it is embedded in the cement board 3 and the bonding strength is extremely high, the pulling force of the mounting bracket 5 acting on the composite board 1 can be greater than the tensile force, so that the composite board 1 falls off from the concrete frame 37. There is little risk of doing so.

FIG. 8 shows another embodiment of this invention, which differs from the previous embodiment in that a counterbore 4a is provided in the through hole 4 of the heat insulating material 2. In addition, the 8th
As shown in the figure, for the heat insulating composite boards 1 and 6 in which a wire with a wire diameter of 2φm/m was embedded as the mounting bracket 5 in the size shown in the figure, a pulling force of 2000 kg was applied to the wire, but This wire did not come out of the glass fiber reinforced cement board 3 in both the heat insulating composite board and the glass fiber reinforced cement board 3.

This idea is as described above, and the mounting bracket is made of wire and its base is buried in a fiber-reinforced cement board, so the base and cement board are surrounded by concrete and fibers. It can be firmly connected without causing insufficient penetration, and therefore even if an external force is applied to the heat insulating wall formed by the composite board and the concrete frame, the phenomenon of the composite board falling off can be almost eliminated. Furthermore, since the entire curved part of the mounting bracket is inserted into a through hole provided in the insulation material, it is easier to position the mounting bracket than when the insulation material is passed through each wire section that makes up the curved part. The fitting operation can be easily performed, and the composite plate can be manufactured easily.
